Me and my partner have unprotected sex quite regulary. We had it while I was fertile but not on the day I ovulated,the day before we did. A week after I ovulated my stomach start feeling really weird and I was getting uncomfortable twinges and cramps, mailnly in my left side,the cramps were pretty bad. I usually get cramps 1/2 days before my period but this was a week before. Done a test and it came back negative. So lately I have been having headaches,extremely tired,constipation, more gasy(sorry)and very sore tender breasts, which I never ever have. Today what I thought was my period came, one day late(no big deal) but its very strange, i have very slight cramps, I am usually in agony, and brown discharge,very light amount of discharge too and when i wipe its brown. This has never happened as I usually get very heavy red flow but have never had anything like this. Please help im very confused. Thanks everyone
